asagna;

Be it known that I, Nuns P. smem g 1 citizen; of the United States,and'a resident of the city of Chica aflin thecounty of Cook and State ofIllinois, have invented certain new and useful Improvements in ArmoredTlres; and I do'hereby declare that the fol lowingis aQi'iIlLQclear,andexact description of the sameyreierencehelng had to. the accompanyingdrawings, and to the numerals of reference marked thereon, which form apartof this specification.

This'invention relat s to an improved type of tire constructiolrwhereinall "the easy resiliency of the ordinary pneumatictire is obtainedwithout thezuse of air under presto proyidea the constructed to sustainheavy sure, I wherein the reinforcing members which doi not'only act toresiliently sustain" thelo'ad? carried by the tire, but further act asan armor to resi'stinjury to the'tire'.

Itis an objecttherefore of this invention loadefinfla resilient mannersimilar "to penumatic tire, "and yet' without the, use of air underpressure, so that in theevent of leakage" or puncture of the tirecasing, no harm or injury ca -aris obi ect' of inyention to employing Ia stiff, resilient is lalso lfan construct a inre .wirefwound ina.series of coils with the coils closely adjacent one another andinterlaced by. auxiliary means and held secured by inc-- tallioresilientbaiids"i 'and invested with a rubber or composition coveringytoprotect and inclose the samefand obviate noise n operation;

It isjalso an object of this inventionto construct aitire havingametallic body of flexible .nature cariable of sustaining great loads,and invested with a rubber-tread or coyeringitoinsure'noiseles'soperation of the ftireion the road and as well to inclose and protectthe metallic structure; j 7

Fig.8 is a fragmentary top View oiithe retaining means at the junctionofsaid inthe principles of my invention. Themetallic body of the tireconsists of inner an outer coils Wound longitudinally around and from asingle strand of wire, the inner coil being denoted by the referencenumeral 3, and the outer-coil by the reference numeral 4. Interposedbetween said inner and outer coils 3 and 4, at points around the tire,are groups of resilient metal straps 5, each group comprising threestraps, as clearly shown in section in Figs. 2, and 6,,andintermediateeach of said strap grouPS is a constructed of corln althonghof course, any suitable material; may beused for the purpose. The wirecoils are provided with an outer investment of rubber, composition,fabric. or other Suitable material 12, oflsubstantially a sealing natureand having an inner circumferential gap 13 to permit removal of theinvestment. 12, in order that the interior of the tire may be lubricatedto; permit easy :action' of the resilient coils and straps inresistingdeflection. Cllheinvestment 12, is slit transversely along itsouter periphery, and the ends thereof, are adapted toJoe connectedibymerely ulcanizing the-same w n. n v l pp d R a i such as shown in Fig.4, or by other means hereinafter described, i

' Secured in-theends or extremitiesof said investment as shown in Figs.7 ,and 8, are staples 14 and 15, adapted to extend between oneanother,as shown in Fig. 8, and

to receive a pin16, inserted: therethrough as shownin Figs,1 7 and 8, tohold the inuestment;.member 12, securely around the wire coils. At thejunction of the meeting ends of said investment member or strip 12,thematerial is cut away or formed at an angle as clearly shown in Fig. 7to receive .a stripof similar material 17, inserted therein whichma'yrthen e vul anized thereto to "conceal and cover" the connectingmembers 14, 15, and 16. Secured on the outer surface or. treadof'theinvestment 12, are a --plurality of disks 18, aflixed thereto byrivets 19, or other suitable means.

The operation is as; follows:

The-body of the tire formed by the inner gandiouter coils 8 and 4, andassociated with the respective straps or bands 5 and 7 and Secured in.the groove or channel formed between the inner flanges 9, resilient coreelement 11, preferably mounted on the interior rim 89, may be used; asso constructed if desired without the investment member 12, but due tothe extreme conditions to which tires are subjected, it is preferable toinclose the mechanical elements in the removablcinvestmcnt 12 thusobviating noisy operation thereof and as well permitting the mechanicalelements to be oiled and lubricated to facilitate their operation whensaid investment is removed. i i

- The "springy construction of the body' of the tire gives the same easyriding qualities of a pneumatic tire, and it is, o' feourse, unnecessaryto use air under pressure for the purpose, The auxiliary core'm'embe'r11, also of resilient material, is provided to reinforcethe tire if forany reason the same should be unduly deformed,

I amaware that various details of construction 1 may be varied through awide range without departing from the principles of this invention,and]; therefore do not purpose limiting the'patent granted otherwisethan necessitated by the prior art.

In a resllient tire of the class described, a plurality of coils of wirewound one Withother, groups of slotted retaining straps, means engagingin said slots to hold said' straps around said coils, and an investmentof material around i the exterior of said straps; a

7. In a tire of the class described, concentric coils formed from aunitary wire,

a retaining means therefor, and interlacing means disposed therebetweenfor holding said coils connected to one another. a

S. In a tire'of he class described, WiIQf coils disposed one Withintheother, slotted straps for retainingthe' same in'position, wiresinterlacing said coils one to i another,

and flanged means adapted to receive said straps attached thereto. g 9.In a tire of the class described, coaxial Wire coils disposed one.Within the other,

means for retaining and holding the same associated With one another, acore member, and flanged means for supporting said means and saidmember.

10. In a tire of the class described, Wire coils one surrounding theother, means for retaining and holding the same associated with oneanother, a resilient core member, an interior flanged rim for supportingsaid means and said member, and an investment of material fitting aroundthe exterior thereof.
